Yea, I don’t see a point of criticizing minutiae from a thesis that has already been accepted, but I agree, the graphs look out of place and generally not in the same style of the other text. Also, I guess I am just really used to latex’s font, it just automatically gives an academic style that I do t get from this. Again, pure personal bias.
If anyone else is looking to make graph with typst, this can be done with https://cetz-package.github.io/ -- which is inspired by Tikz from the LaTeX world -- or https://lilaq.org/ which seems more appropriate for this type of data plotting
